why would you have to use a pulley to get the 1 ph up to speed? Doesn’t it have a start capacitor?

I believe he means to get the cutter head to the same speed using the 1725 rpm motor as the 3450 (3 phase) rpm motor turned it. Yes you could do that but you are correct when you say you would be losing something. You lose your power when you change pulley sizes and it will never cut right at the lower speed. It will make rough cuts or you will have to feed the stock at a very slow rate. You will not be happy with it. I can’t believe you need more than 2/3 or the 5 hp. You would have over 3 hp. that is a lot but maybe not for the 20”. That is a big planer. Look for a motor. They are for sale but plane to pay $500 for a new on and you will need to know the frame size so it will mount.
